本文講述了Android開發實現圖片圓角的方法。分享給大家供大家參考，具體如下：
Bitmap myCoolBitmap = ... ; // <-- Your bitmap you want roundedint w = myCoolBitmap.getWidth(), h = myCoolBitmap.getHeight();Bitmap rounder = Bitmap.createBitmap(w,h,Bitmap.Config.ARGB_8888);Canvas canvas = new Canvas(rounder);Paint xferPaint = new Paint(Paint.ANTI_ALIAS_FLAG);xferPaint.setColor(Color.RED);canvas.drawRoundRect(new RectF(0,0,w,h), 20.0f, 20.0f, xferPaint);xferPaint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.DST_IN));canvas.drawBitmap(myCoolBitmap, 0,0, null);canvas.drawBitmap(rounder, 0, 0, xferPaint);
或者：
public static Bitmap getRoundedCornerBitmap(Bitmap bitmap) { Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Config.ARGB_8888); Canvas canvas = new Canvas(output); final int color = 0xff424242; final Paint paint = new Paint(); final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight()); final RectF rectF = new RectF(rect); final float roundPx = 12; paint.setAntiAlias(true); canvas.drawARGB(0, 0, 0, 0); paint.setColor(color); canvas.drawRoundRect(rectF, roundPx, roundPx, paint); paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN)); canvas.drawBitmap(bitmap, rect, rect, paint); return output;}更多關于Android相關內容感興趣的讀者可查看本站專題：《Android圖形與圖像處理技巧總結》、《Android開發入門與進階教程》、《Android調試技巧與常見問題解決方法匯總》、《Android多媒體操作技巧匯總(音頻,視頻,錄音等)》、《Android基本組件用法總結》、《Android視圖View技巧總結》、《Android布局layout技巧總結》及《Android控件用法總結》
